Application timing

Refer to label for various timing of application on registered crops.


  • FASTER HARVEST typically 4-10 days after application
  • CONTACT ACTIVITY that provides fast drydown of green material
  • SAFE to use on crops that will be used for seed

Performance tips

1) Water volume

  • Ground: minimum 20 gallons/acre
  • Air: minimum 4 gallons/acre

2) Use of adjuvant is required

  • Add non-ionic surfactant such as AGRAL 90 at 1 L per 1,000 L or LI 700 at 2.5 L per 1,000 L 

3) Performance may be enhanced when applied in the evenings or on cloudy days

Pre-harvest challenge

Time alone is not the enemy. The potential losses that the passing of time causes is where crop management strategies are required. It’s simple, shortening the time to get the crop in the bin protects the quality and creates a more valuable crop. In addition, time management is a requirement of today’s farms.

Nufarm solution

DriFast desiccant delivers another option to help growers manage their harvest. DriFast (Group 22) contains the trusted active ingredient, diquat that’s similar to Reglone, providing Canadian farmers with another tool to dry down the crop quickly allowing for a more efficient harvest and higher quality grain.
